The non-reactive fluid power tool for surface cleaning has a body 1 with a passage 2 of a working fluid supply pipeline. The barrel 3 is connected with the body 1. The high pressure working fluid pipeline is connected to the barrel 3.

The tool comprises a protective strap 5 fixed to the body 1, an adapter 6 mounted on the body 1, a passage 2 of the pipeline for supplying the working fluid of the body 1 to the adapter 6. It is provided with a hose (7) connected to a high pressure source (not shown) through. The working fluid flow regulator 8 mounted to the body 1 has a control knob 9 and communicates with a working fluid supply pipeline. A tailpiece 10 is provided at the free end of the barrel 3, with the ejector 11 and the high pressure chamber 12 behind the barrel outlet 3 toward the high pressure actuating nozzle 4 with respect to the barrel 3. ).

The support clamp 16 is mounted to the regulator 15 of the ejector 11.

The ejector 11 is formed axially symmetrically through a passage 17 made in the tail piece 10 and arranged around the barrel outlet 3. The regulator 15 of the ejector 11 is made in the form of a rotatable adjustment ring 18 mounted to a mouthpiece 13 of the barrel 3, which ring 18 is a mouthpiece 13.

The tool operates as follows.

The working fluid under the predetermined pressure passes from the working fluid source (not shown) through the hose 7 and through the adapter 6 to the passage 2 of the pipeline for supplying the working fluid of the body 1. Next, the working fluid is supplied to the flow regulator 8, where the flow rate is adjusted by turning the control knob 9. The working fluid having a predetermined flow rate is supplied to the high pressure chamber 12 of the tail piece 10 through the barrel 3 and from there to the high pressure operating nozzle 4.

A working fluid is sprayed from the high pressure working nozzle 4 onto the surface to be treated (not shown) to clean stratification, metabolites, corrosives and the like. During the outflow of the working fluid from the high pressure actuating nozzle 4, a counterthrusting force acting on the operator through the body 1 appears. To compensate for this back thrust, the tail piece 10 is provided with an axisymmetric passage 17 formed together with the ejector 11 of the high pressure chamber. In order to control the flow rate of the ejector 11, the tool is made in the form of an adjustment ring 18 which can be rotated with respect to the tail piece 10 of the barrel 3, and the mouth piece attached to the tail piece 10. A regulator 15 having an adjustment port 14 of 13 and an opening 19 superimposed thereon is provided. By turning the ring 18, the flow rate of the ejector 11 is controlled due to the interaction of the opening 19 and the port 14, depending on the pre-adjusted flow rate and the pressure in the working fluid supply pipeline. The draft changes. The tool is provided with a clamp 16 on the regulator 15 of the ejector to place the high pressure actuating nozzle 4 in a stable position with respect to the surface to be treated (not shown).

The shaft 20 of the barrel 3 may be straight (FIG. 1) or curved (FIG. 4) for the co-current jet outlet from the operator's work area. Thus, the working conditions of the worker are improved and the productivity is improved. The curved axis 20 of the barrel 3 can also be used to treat structurally complex surfaces and surfaces and components in inaccessible places.

In some embodiments of such a tool, the adapter connects the barrel 3 and the body 1 and allows the barrel 1 to be effectively replaced with other properties such as the ejector 11, the head piece 13, and the like. It may have 21.
